Securing the Workpiece

You'll need some sort of option to hold the workpiece, from the basic double-sided tape (this is described in the makercam.com tutorial) to clamps along the edge of the piece to more sophisticated work-holding methods such as V- and T-slot beds w/ custom clamps or a vacuum table (Forum discussion).

A comment on spacing --- some sort of ratio (phi?) is likely more useful than even spacing.
